TSD functionality is only available if the TSD option is enabled on your licence.
There are two types of time series data (TSD) objects in InfoAsset Manager: Scalar Time Series Data and Spatial Time Series Data. These objects provide an intermediate store between external data sources (such as SCADA/telemetry or RADAR) and a time series data source.
The main differences between Scalar and Spatial time series data objects are shown in the table below.

Information stored in each time series data point |
In a Scalar TSD, each time series data point has no geometry (i.e. no polygons) and has only one value. |
Each time series data point in a Spatial TSD stores a number of polygons and a value for each of these polygons. |
Number of datastreams and data sources |
Scalar TSDs can have many streams and data sources defined. |
Spatial TSDs can only contain one stream (and only one data source). Spatial data requires much more storage than scalar data so limiting Spatial TSDs to one stream significantly helps partition the storage. Also, a model tends to have many scalar data sources (and only a few spatial data sources) so it is more manageable to keep a number of streams together in one Scalar TSD rather than have many tree objects. |
Display in InfoAsset Manager |
Scalar values are displayed alongside their timestamp in a grid (see Time Series Data Grid). |
Spatial time series values are displayed in the GeoPlan as a theme. See Displaying Spatial Rainfall on the GeoPlan. |
See the Scalar Time Series Data topic and the Spatial Time Series Data topic for further details.
See the Working with Database Items topics for details on how to create, open, edit, save or delete Scalar and Spatial time series data objects.
The specific differences in the way TSD objects behave compared to the other database items are:
The procedure to view the time series data points for an individual stream inside a time series data depends on the TSD object type:
The Time Series Data Grid, where the data points can be viewed and edited (if required), is opened.
An example is included in the Delete Unused Time Series Data Dialog topic.
You can edit data contained in time series data objects. See Editing Time Series Data for more information.
Time series data may be updated from external data sources. See Updating Time Series Data for further details.
